Fixed linting against ansible-core version 2.14

This PR fixes some linting errors for the ansible-consul role, applied on Ansible version 2.14.

I've used this version since ansible-core 2.14 is still supported (https://endoflife.date/ansible-core) and ansible-core 2.8 is unsupported.

Most notable changes:

switched systemd to ansible.builtin.systemd_service module (see: https://docs.ansible.com/ansible/latest/collections/ansible/builtin/systemd_module.html and https://docs.ansible.com/ansible/latest/collections/ansible/builtin/systemd_service_module.html#ansible-collections-ansible-builtin-systemd-service-module)
added file parameter for ansible.builtin.import_tasks (see: https://docs.ansible.com/ansible/latest/collections/ansible/builtin/import_tasks_module.html#parameter-file)

I was not sure if ansible.windows can be removed as a requirement now, as it is replaced by community.windows in newer Ansible versions.

While testing locally with Molecule, I've encountered some errors like:

Command: molecule --base-config molecule/_shared/base.yml converge --scenario-name debian-11

Error:

Prepare stage:

TASK [Install OS packages] *****************************************************
fatal: [localhost]: FAILED! => {"changed": false, "module_stderr": "sudo: a password is required\n", "module_stdout": "", "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error", "rc": 1}

So maybe someone can give me a little hint here.

Otherwise, I still hope that this PR will be reviewed and possibly successfully merged. Please write to me if there is anything missing in this PR!
